mourn-msrnnsme APPARATUS.

Application filed June 16,

My invention relates to liquid dispensing apparatus and particularly to means for-completely draining the liquid in the elevated reservoir back to the storage tank. In such apparatus the elevated reservoir is made of glass, hence this particular type is generally called visible dispensing apparatus, and they are used principally for dispensing gasoline.

To decrease fire hazard some means for completely draining the contents of the elevated reservoir back to the storage tank is usually required, and one means is through the discharge hose and nozzle into the overflow pipe and thence to the storage tank.

The crude idea is set forth in the patent to Edward N. Kern, No. 1,210,812, issued January 2nd 1917.

The rincipal object of this invention is to provide means for ensuring the complete draining of the elevated reservoir whenever the hose nozzle is fixed in the projection from the overflow pipe and the pump locked up as for the night.

My invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation of a visible dispensing apparatus of the so-called dry hose type that is the type in which the hose is not filled with gasolene at'the time service of gasolene to a customer is begun, shown from the discharge and drain-back side, with the hose nozzle in drain-back position as when locked up for the night;

Fig. 2 is the apparatus turned a one-fourth turn to the left and with part of the hose, the pedestal and its cap broken away to expose the interior mechanism, and with the top head and adjacent parts of the elevated reservoir broken away; and

Fig. 3 is an under plan view of the valve.

reservoir at such a height that when the reservoir is filled ready to serve customers the quantity .equals the maximum amount to be dispensed at one time, generally five or ten gallons; and it is adapted to convey ex cess liquid back to the storage tank.

From a T o in the overflow'pipe extends to the side through the pedestal A an angular projection 0 terminating at'the top in a fitting 0 to which is pivoted a cap 0 Gasoline I flows from the reservoir 0 through the pipe 0, valve 0 hose H and nozzle D into the customers car tank or other container when the apparatus is in service, and back to the underground storage tank when the nozzleis inserted into the fitting 0 when the apparatus is locked up when temporarily put out of service.

The valve '0 is normally T-kept closed by the weightedvalve lever Which is manually raised and held while serving gasoline. The valve stem 0 of the valve 0 is in axial alignment with an extension thereof 0. c and 0 have their abutting ends united so that the valve stem and its extension will rotate together as though unitary in the following or any other convenient manner :The valve lever 0 is pinned to the stem 0 and a coupling a is pinned to the extension 0 and bolted to the lever c The extension of is journalled at 0. A lever c is pinned to the extension 0 and through a hole in the outer end of 0 passes loosely a connecting rod 0 and said rod is supported by the nut c. At its lower end 0 is similarly secured to the inner end of a bell crank lever 0 and 0 is pivoted at 0 to the'casing A. The outer end of the lever 0 is so shaped and positioned as to cause it to be pressed inwardly toward the casing A, that is to the right as shown in Fig. 2

when the spout of the nozzle D is inserted in fitting 0 and the nozzle guard rotated against the outer end of the lever a. pressing it toward the housing, so as to put the apparatus in position to be locked up, as when the apparatus is being put out of use for the night. This depresses the inner end of the lever 0 and through the rod 0 pulls down the outer end of the lever 0 rotates the valve stem 0 -0 raises the weight 0 and opens the valve 0 A pad-lock 0 holds the nozzle guard 0 securely against a bracket 0 fixed to the housing A, maintaining the arts in the position just described. All liquid remaining in reservoir C will then be drained back to the source of supply through the hose H. q

I claim as my invention and desire to secure by Letters Patent of the United States:

1. In a liquid dispensing apparatus, the combination of an elevated reservoir and support therefor, means for supplying liquid to said reservoir, a conduit for draining said reservoir, a hose attached to said conduit, a nozzle on said hose, a valve controlling the flow of liquid through said conduit into said hose, means for normally keeping said valve closed, means wholly out of contact with the liquid in said apparatus for opening said valve against the action of said closing means, an overflow pipe to convey backfrom said reservoir to the source of supply all liquid therein in excess of a predetermined quantity, a connection to said overflow pipe forming a socket to receivethe outlet end of the nozzle and means on said nozzle above its spout by which said Valve opening means may be actuated when the nozzle is in the socket to open said valve.

2. In a liquid dispensing apparatus, the combination of an elevated reservoir and support therefor, means for supplying liquid to said reservoir, a conduit for draining said reservoir, a hose attached to said conduit, a nozzle on said hose, a valve controlling the flow of liquid through said conduit into said hose, means for normally keeping said valve closed, means wholly out of contact, with the liquid in said apparatus for opening said valve against. the action of said closing means, an overflow pipe to-convey back from said reservoir to the source of supply all liqiiid therein in excess of a predetermined quantity, a connection to said overflow pipe forming a socket to receive the outlet end of the nozzle, means on the uard of said nozzle by which said valve open ng means may be actuated when the nozzle is m the socket to open said valve, and means for holding said valve opening means in position with the valve open. a

3. In a liquid dispensing apparatus, the combination of an elevated reservoir and support therefor, means for supplying liquid predetermined quantity, a connection tosaid overflow pipe forming a socket and means on a part of said nozzle that does not enter said connection for actuating said lever shifting means when the nozzle is in the socket.

4. In a liquid dispensing apparatus, the combination of an elevated reservoir and support therefor, means for supplying liquid to said reservoir, a conduit for draining said reservoir, a hose attached to said conduit, a nozzle on said hose, a valve controlling the flow of liquid through said conduit into said hose, means for normally keeping said valve closed, a lever for opening said valve against the action of said closing means, means for shifting said lever, an overflow pipe to convey back from said reservoir to the source of supply all liquid therein in excess of a predetermined quantity, a connection to said overflow pipe forming a socket, means on a part of said nozzle that does not enter said connection for actuating said lever shifting means when the nozzle is inthe socket and means for holding said parts in valve open position.

In testimony whereof I have hereunto set my hand.
